Where can I find data on the interbank lending market?@JoshuaUlrich I've read the topic you mentioned before posting my question. I'm actually asking for a very specific data (lendings bank-to-bank), I didn't find it in neither that topic, nor through google, nor in papers).

Home/hobbyist quant trading - possible to profitable or just an intellectual hobby?I wouldn't see it as a complete off topic.
